  • Patent number: 9760808
    Abstract: An image pickup device transmits to a server a transmission sample including a detection image detected by a first detection section from a transmitting/receiving section under the control of a transmission sample control section. The server performs detection processing that requires more resources than those of the first detection section on the detection image transmitted by a second detection section from the image pickup device, and determines whether or not the detection image in question is spurious, based on a second detection score which is thereby obtained. A transmission frequency deciding section generates transmission frequency control information such as to raise the transmission frequency by an image pickup device that has a high frequency of spurious detection; a transmitting/receiving section transmits the transmission frequency control information to the image pickup device.

  • Patent number: 9639766
    Abstract: An image monitoring system that efficiently utilizes a network band and decrease the processing load of a server is provided. A second image decision processor analyzes an extracted image transmitted from a monitoring terminal, and evaluates the quality (reliability) of the extracted image. A reliability decision unit outputs an individual ID of the analyzed extracted image to a load estimation unit when the numerical value from the analysis output by the second decision processor becomes less than the preset threshold. The load estimation unit estimates the server processor load of a server and the network load. A resend request unit controls the resend request for an individual ID output from the negative load estimation unit corresponding to the server processor load and the network load.
